How to reduce solder paste waste
Sep 08, 2022
09-08
2022
Solder paste manufacturer's suggestion 1: Choose a suitable solder paste.
The main component of solder paste is a paste made by mixing metal powder and flux. Can the electronic components be well attached to the circuit board during the production process of the SMT manufacturer? The quality of lead-free solder paste is a very critical control point. A suitable solder paste can not only improve the soldering yield of the production line, but also greatly improve the soldering performance of the circuit board, which is the most reliable guarantee for the soldering quality of the circuit board. A good quality solder paste will have the following parameters.
The reason for the large amount of tin slag in the tin bar?
Sep 07, 2022
09-07
2022
There are many reasons for the generation of tin dross, involving product quality, operation methods and maintenance methods of machinery and equipment, welding materials, etc. It is often encountered that many factories do not care about the height of the tin surface. Some tin bar factories with the same specifications and series use only about 5KG/8 hours of tin dross, while others use more than 10 kg/8 hours of tin dross.
Environmental requirements for lead-free solder bars in the electronics industry
Sep 07, 2022
09-07
2022
The earliest and most important driving force for the electronics manufacturing of lead-free products mainly comes from two EU directives (WEEE and ROHS). These regulations explicitly prohibit the use of heavy metals such as lead, cadmium, mercury and hexavalent chromium in electrical and electronic products. PBB and PBDE are two flame retardant materials.
What is tin bar? The role of tin bar?
Sep 07, 2022
09-07
2022
Tin bar is a solder product. There are two types of tin bars: leaded tin bars and lead-free tin bars, both of which are used for circuit board soldering. Made of pure tin, good wetting and fluidity, easy to tinplate. The solder joints are bright and full, and there will be no welding and other undesirable phenomena. Add enough antioxidant elements, strong antioxidant ability. Made of pure tin, reducing tin dross and reducing unnecessary waste.
What should be paid attention to when welding lead-free solder wire
Sep 07, 2022
09-07
2022
When using lead-free solder wire, you must be careful not to touch the road surface with your hand, and feel that the battery is charged, including the solder pen cover, which may cause an electric shock accident. Professional technicians should also wear protective clothing as much as possible during the operation, mainly because liquid organic solvents will be generated during the whole process of electric welding, and it is very easy to burn and blister without wearing protective clothing.
How many degrees should the lead-free tin bars be set properly during use?
Sep 06, 2022
09-06
2022
Generally speaking, we should set the appropriate degree during use. I believe that many technical experts will discuss this issue. The general temperature of lead-free solder bar welding is set to 280 plus or minus 10 degrees, because there is no preheating for manual dip soldering. , so the temperature setting is generally higher.
Is the solder rod and the welding rod the same welding material?
Sep 06, 2022
09-06
2022
First of all, it is certain that solder bars and welding rods are not the same thing. solder bars are a kind of product in soldering tin. The main components are alloys composed of tin, silver, copper, lead and other metals. According to environmental protection standards, they can be divided into lead Two kinds of tin bars and lead-free environmentally friendly tin bars are widely used in the electronics industry, and are generally used for circuit connection of integrated circuits or welding of small items on circuit boards.
The main factors of tin wire fried tin and how to prevent it
Sep 06, 2022
09-06
2022
The phenomenon of tin explosion and tin explosion means that when the high-temperature soldering iron head touches the solder wire during the soldering operation, it will make a cracking sound, and at the same time, the molten tin will splash and pop out some small tin beads of bright color. Tin phenomenon.
What is the difference between solid core solder wire and flux cored solder wire?
Sep 06, 2022
09-06
2022
The flux-cored solder wire leaves a channel inside for placing the rosin flux, which can better help product soldering. The solid core solder wire, as the name implies, refers to the solid core of the solder wire, and no rosin flux is poured in the middle, hence the name solid core solder wire.
How to deal with the clogging of the tin wire of the automatic soldering machine?
Sep 05, 2022
09-05
2022
Check the wire feeding speed of the tin wire. Under normal circumstances, the wire feeding speed should be less than 60mm/s. If the wire feeding speed is too fast, the tin wire may be pushed to the PIN before it can be melted, which may easily cause tin blocking.
